Description

Technical Field

[0001] The utility model relates to the technical field of trolley brake devices, in particular to a full-steel tread trolley brake device. Background Art

[0002] A mobile trolley, also known as a cargo trolley or cage trolley, is a unit-sized containerized device equipped with four casters for transporting and storing materials. It is commonly used for distribution in large supermarkets or for inter-process logistics in factories. Mobile trolleys are a valuable tool for the logistics and manufacturing industries, allowing production lines to maximize their space and store products.

[0003] In existing technology, after the all-steel tread trolley is transported to the machine location, the manual brake is unlocked and adjusted, releasing the brake disc. The wheel rim drives the large I-shaped wheel to start curling the outer square tube. After curling is completed, the manual brake is adjusted to complete the braking process. This manual braking process is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a full-steel trolley brake device to solve the problems raised in the above background technology.

[0006] One side of the upper end of the rotating rod is rotatably connected to a cylinder, and the end of the cylinder away from the rotating rod is rotatably connected to a rotating plate. The rotating plate is L-shaped and rotatably connected to the frame through an axle pin. A buffer is provided on one side of the rotating plate.

[0007] Preferably, an angle steel is rotatably mounted on the lower side of one end of the rotating rod, and the lower end of the angle steel is fixedly mounted on the vehicle frame.

[0008] Preferably, a connecting plate is fixedly mounted on one end of the rotating rod, and the connecting plate is rotatably connected to the mounting bracket.

[0021] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The cam 3 is connected to the front and rear frames of the vehicle body 1, and the cam 3 is connected to the rear frame 1 by a plurality of levers 16. The cam 3 is connected to the rear frame 1 by a plurality of levers 17. The cam 3 is connected to the rear frame 1 by a plurality of levers 18.

[0023] A fixing plate 7 is provided at the upper end of the connecting plate 4, and the fixing plate 7 is fixedly mounted on the vehicle frame. A connecting rod 8 is fixedly mounted on the lower end of the fixing plate 7, and a spring 9 is fixedly mounted on the lower end of the connecting rod 8. The lower end of the spring 9 is fixedly connected to the upper end of the connecting plate 4. When the spring 9 is in a balanced state, the brake wheel 6 contacts the rims of the large and small I-shaped wheels to achieve automatic braking.

[0024] A triangular block 10 is fixedly installed on one side of the upper end of the rotating rod 3. The upper end of the triangular block 10 is rotatably connected to the output end of the cylinder 16. The end of the cylinder 16 away from the rotating rod 3 is rotatably connected to the rotating plate 13. The rotating plate 13 is L-shaped. The rotating plate 13 is rotatably connected to the frame through an axle pin 14. The axle pin 14 is rotatably connected to the frame through a bearing. The outer end of the axle pin 14 is fixedly connected to the outer wall of the rotating plate 13. A grip rod 15 is fixedly installed on the upper end of the rotating plate 13. After leaving the machine position, swinging the brake grip rod 15 can achieve manual unlocking and braking.

[0025] A buffer 12 is provided on one side of the rotating plate 13, and an ear block 11 is fixedly installed on one side of the upper end of the frame near the rotating plate 13. The buffer 12 is fixedly installed on one end of the ear block 11. When the output end of the cylinder 16 is extended, it drives the end of the rotating rod 3 with the brake wheel 6 to rotate downward, and the other end of the cylinder 16 drives the rotating plate 13 to rotate. The rotating plate 13 contacts the buffer 12 on one side of the ear block 11 and prevents the rotating plate 13 from rotating. The brake wheel 6 moves downward and separates from the rims of the large and small I-shaped wheels to achieve automatic unlocking.

[0026] When this device is working, the all-steel tread trolley is taken to the work station by the AGV trolley fork. After the tread trolley reaches the designated work station, the driving wheel presses the outer flat iron of the large I-shaped wheel, and the starting cylinder 16 is pushed forward to push the rotating rod 3 to automatically lower the brake wheel 6 to achieve automatic unlocking. After the curling is completed, the starting cylinder 16 is retracted backward, and the brake wheel 6 is pulled by the spring 9 above, and the brake wheel 6 is lifted upward and automatically close to the rims of the large and small I-shaped wheels to achieve automatic braking; after leaving the machine position, the swing brake handle 15 can be swung to achieve manual unlocking and braking. This structure realizes automatic braking and unlocking, greatly reducing manpower. Even if the tread trolley fails, it can be manually unlocked.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
